Succeeding from failures, Ms. Thuy Hong always has a passion for food in her heart Accept failure to move forward Born and raised in Hanoi city, Ms. Vu Tran Thuy Hong is the youngest in a family of 4 sisters. Since childhood, her mother had to work from early morning until late at night, so she taught the sisters in the house to cook from a young age to know how to take care of each other from a young age. This is the beginning of her passion for food. Growing up, due to the good fortune of traveling a lot, she has been exposed to culinary cultures in the country and the world, from which the passion for food has grown in her. Like most young people who are enthusiastic but inexperienced in starting a business, Thuy Hong started her own business according to her own experience, without a method and without a foundation of business knowledge and experience. Therefore, she has encountered the most basic difficulties from team operation, financial management, human resources, restaurant communication to time management… “At that time, technology, the internet had not yet developed and social networks did not exist as it is now, so I had to depend on my brothers and friends in the same industry to guide, support and instruct me to grow up. from accumulating knowledge, experience, and gradually improving herself”, said Ms. Thuy Hong. In order to receive more and more support and love from customers, Ms. Thuy Hong has boldly tried many different culinary schools. And in order to accumulate a lot of experience, she has met many failures, but after each fall like that, Thuy Hong always tells herself to try harder, to look at the positive face is to take it as a lesson and an action. strength to make the next steps stronger, on the right path. She said: “The most memorable trip was when I opened my first restaurant with the Vietnamese restaurant model. Daily cooking and professional restaurant cooking are two completely different fields. capital of 100 million borrowed from friends, pressure comes from shopping design for restaurant, monthly rent, first few months without customers, loss of customers, staff management, optimization of raw materials, development new dishes … have really become a big burden and there were times when it seemed to make me fall.” But in the face of such difficulties, she said to herself: no matter how difficult it is, I am luckier than many others, because I still have a place to return to, that is, my family is always supportive and loving. ; There are friends who are always there to encourage and support, and even diners who are always smiling with delicious dishes that Thuy Hong has poured all her heart into. That’s what helped her get through that crisis. In order to receive more and more support and love from customers, Ms. Thuy Hong boldly tried in many different culinary schools. Thereby, she also realized that at every start-up with a new model, everyone needs to learn more, will encounter new problems and difficulties, but to be successful, just don’t wallow in difficulties but focus on the challenges. focus on the solution. And more than that, she always takes customers as the center, bringing customers services and products that exceed expectations. Authentic Vietnamese cuisine Her love for the culinary industry never goes away, she has burned her passion to launch a Vietnamese food brand with Vietnamese essence and soul – that’s also the reason why Kop Co Hong brand came out. life and is loved and accepted by many customers as it is today. With the snack brand Kitchen Co Hong, she has launched quintessential fast food or appetizers, which are most loved by customers with her culinary experience. The food is delivered to your home so that customers can enjoy it without having to go to the restaurant or go to the kitchen. “The first product that Kop Co Hong launched was VuVu salted chicken feet, a street food of the Vietnamese people. It was chicken feet soaked in spicy and sour chili salt, which was responded by male, female, old and young customers as ” Addictive” by the chewy, chewy flavor of chicken feet mixed with the strong aroma of green chili, reminiscent of the dear memories of Vietnamese people with stories, at the drinking table, and in the trays of rice. In the coming months, Kitchen Co Hong will release dishes such as dried chicken with lemon leaves, peanuts wrapped in garlic and chili, fish skin with salted eggs, fried rice with shrimp paste…”, Ms. Thuy Hong shared with joy. twinkle. Co Hong Kitchen is always picky about choosing delicious ingredients, Vietnamese-style recipes, combining the use of the most advanced technologies. Talking about the secret to having fresh and delicious products with many customers, Ms. Thuy Hong said, Kitchen Co Hong is always picky about choosing delicious ingredients, recipes with Vietnamese flavor, and results. Using the most advanced technology today such as food irradiation technology to help preserve the freshest and safest products. Irradiation technology is one of the technologies that must be used for some food products in order to meet export standards to the US and Europe. Through Vietnamese-flavored dishes, Ms. Thuy Hong wishes to bring customers meals with loving family, helping them save time and still have a warm meal with their family. Help the brothers have more dishes with friends, boys and girls have more fun snacks in every fun. Currently, Co Hong Kitchen products are distributed in agents, convenience stores, and grocery stores nationwide, but anyone can easily order products via shopee, lazada or facebook. and instagram. Succeeding from failures, Ms. Thuy Hong always has a passion for food in her heart, and that fire is getting warmer when she receives positive feedback messages from customers, so that she can more sources of encouragement, continue to create delicious, strange and bold Vietnamese dishes in Hanoi.

Technicians of the Center for Radiation Technology and Biotechnology (Nuclear Research Institute, based in Da Lat city, Lam Dong) next to a radioactive projector that causes mutations in plants. The Center for Radiation Technology and Biotechnology (Nuclear Research Institute) is a unit that regularly applies radiation techniques to select and create mutant varieties on plants. Especially in the past time, the orchid and bonsai market has been extremely active, many customers have come to the center to irradiate to mutate their plants. The irradiation process is quite quick, with the new technology Gama Cobalt irradiator, this process only takes about 1-2 minutes and is completely automatic. Immediately after, orchid seeds will be taken to the separation room to be cultured in nutrient solution for a certain time. After that, these plants were further isolated many times to select mutant morphologies different from the parent plant. Master Le Xuan Cuong, irradiation technician (Center for Radiation Technology and Biotechnology), said that the number of doses will vary depending on the sample provided by the customer such as tissue samples, branches, seedlings… “After irradiation, it will produce random mutations, beneficial or harmful, regardless of their will” – Master Cuong said. Currently, the Center’s Culture Room is storing many pseudo-crane orchid seedlings that have mutated on the stem and on the leaves. Specifically, the color of leaves and stems have turned white or purple. These are mutant forms that can be seen immediately, for flower color, you have to wait for the plant to grow and flower as usual. According to Mr. Le Van Thuc, Deputy Director of the Center for Radiation Technology and Biotechnology, for flower plants, by irradiation techniques, it is possible to select flower colors or select traits that are resistant to adverse conditions. environmental benefits such as preventing fungal and bacterial diseases on plants. “Compared to natural mutations, the probability is one in a thousand or one million, but using radioactive sources to cause mutations in plants will have a higher probability of hundreds, thousands of times,” – Mr. Thuc analyzed. Application on many plant varieties After irradiation, samples of the fake crane orchids were taken to the separation room to be cultured in nutrient solution for a certain time. Not only orchids, the Center for Radiation Technology and Biotechnology has tested irradiation to cause mutations on Forget-me-not Da Lat flowers, Torenia flowers, and Dendrobium orchids. The results have created many mutant lines in flower color and structure of stems and leaves with great differences compared to the mother plant. Through that, the Center has built up the basic processes of radiation breeding; selection of materials for irradiation, frequency of irradiation, propagation, experimental planting to screen for mutations at phenotypic level, identification of mutant lines at molecular level… According to Mr. Le Van Thuc, the Center’s orientation will continue to promote the field of plant biotechnology and plant breeding, rapid multiplication of plant varieties and conservation of valuable plant genetic resources; continue to develop radiation technology in the selection and breeding of key plant varieties, endemic varieties of Lam Dong province, focusing on selecting and creating new quality varieties on flower, fruit, ornamental and medicinal plants. The culture room of Radiation Technology and Biotechnology (Nuclear Research Institute) houses many mutant plants, which are mainly orchids. Currently, the Nuclear Research Institute has used irradiation techniques combined with In-vitro methods, applying in vitro flowering techniques to quickly select flower color mutations, shortening the selection time. filtering, reducing the cost of isolating mutant lines that previously had to be planted in the field for selection. At the same time, the Institute cooperates with many units throughout the country such as the Southern Fruit Institute, the Mekong Delta Rice Institute, the Central Highlands Agro-Forestry Research Institute, universities: Tra Vinh University, the University of Da Lat,… to handle mutant irradiation on many different crops. Mr. Do Minh Ngoc, Deputy Director of the Department of Science and Technology of Lam Dong province, said that irradiation is a tool and a technological solution for breeding that many parts of the world have implemented. However, the selection and maintenance of mutant traits is very important and requires time and experience for these plants to become a source of seeds for other production industries.

After irradiation, samples of the fake crane orchids were taken to the separation room to be cultured in nutrient solution for a certain time. (Photo: Nguyen Dung/VNA) In Lam Dong – the “capital” of high-tech agriculture of the country, the application of new science and technology in agriculture is increasingly widespread. Especially for the plant breeding industry to preserve rare genetic resources as well as to develop commercial varieties of these plants. Wild Orchid Di Linh is one of such trees. They are not only mass-produced, but also irradiated to create mutations on demand. Di Linh fake crane – a “famous” orchid of orchid players inside and outside Lam Dong province, often sought to buy with many different prices. However with In-vitro technology As modern as it is today, for the first time, the Center for Science and Technology Application (Lam Dong Department of Science and Technology) has successfully studied the process of mass propagation of this plant. Mass breeding The technique of propagation by plant tissue culture (In-vitro) is no longer strange in Lam Dong province in general and Da Lat city in particular. The application of this technology to propagate the species of Orchid Di Linh was first deployed by the Center for Science and Technology Application. The project was completed, completed and accepted by Mr. Phan Quoc Chinh, Deputy Director of Lam Dong Center for Science and Technology Application and his colleagues. To select the original source of quality seed, the people who carried out the project had to collect Gia Hac Di Linh orchids in Da Lat city and Di Linh district, in orchid gardens that met strict standards. Sampled plants must have an average height of 30-40 cm, have 14-16 pairs of leaves, average trunk diameter of about 4mm and be planted in plastic or terracotta pots. Each tree has 4-5 fruits and the physiological ripening rate is not equal. Selected fruits that should be dark green and physiologically ripe, of the specified size, without cracks, were collected for inclusion in the sample. A seedling of the fake crane orchid has had a mutation: the color of the leaves, the stem has turned white or purple. (Photo: Nguyen Dung/VNA) After being cleaned and disinfected, samples of Di Linh imitation crane will be propagated in-vitro according to the following summary procedure: initial culture stage to create buds and clusters of buds; rapid multiplication stage; rooting stage to create a complete plant. These three stages take about 28 weeks, then the seedlings (5cm tall, 4cm long roots, good growth, dark green leaves) are brought to the nursery to plant and take care of. After the next 24 weeks, the plant can be grown with a height of 5-7cm, with 4-5 leaves. According to Mr. Phan Quoc Chinh, plants grown in an In-vitro environment must ensure the conditions of temperature, humidity and light intensity according to certain cycles. In addition to the results of creating a series of fake crane orchids, the project also built a standard process for propagating this plant by the In-vitro method and can be transferred to other units. “During the implementation, we tried to add ripe banana pulp, coconut water to the culture medium. The results showed that shoot formation and shoot growth also increased faster than normal, “- Mr. Chinh said. Very cheap price After finishing breeding process In-vitro, the first 500 orchid seedlings were brought to the nursery at the Don Duong Experimental Station (Don Duong District) and continued to be tested on many different types of media within 3 months. As a result, the rate of plants living outside the nursery reached 90%. Among the types of substrates put into the experiment, coir fiber media helped the plant grow best, the height of the tree reached 5.6cm; The root length is 3.70cm, the survival rate is 95% and the tree has a large stem, dark green leaves, many leaves. A Di Linh Fake Orchid is eligible for sale for 25,000 VND / tree, very cheap compared to the current market. (Photo: Nguyen Dung/VNA) According to Mr. Nguyen Nhu Chuong, Director of Lam Dong Center for Science and Technology Application, after the acceptance of the project, the Center continues to propagate about 3,000 plants to supply domestic and foreign markets at an export price. selling for only about 25,000 VND/seedling. “The method of tissue culture in the laboratory makes it possible to propagate many times larger numbers than natural breeding. Therefore, the price that the Center is selling to the market today is normal,” said Mr. Chuong. From the results of the study, Center for Applied Science and Technology Lam Dong has carried out the development of basic standards for Gia Hac Di Linh orchid seedlings and received by the Sub-Department of Cultivation and Plant Protection. Thereby, the genetic resources of rare forest orchids originating locally are preserved and developed. According to Mr. Ho Anh Dung, Vice Chairman of Da Lat Flower Association, the quality of In-vitro seedlings will ensure higher uniformity and superiority compared to traditional methods, serving the conservation of seed resources. and commercial purposes. The first-line mother plant has been carefully selected, which will help the seedlings to preserve the best characteristics of the mother plant, not only the Di Linh orchid but also precious plants such as Ngoc Linh ginseng, Camellia flower./ .

In a new study published in the journal Acta Astronautica, scientists said, in the future, a dangerous asteroid will plunge itself and collide with Earth. Relatively, an asteroid does not need to be too large to cause severe destruction. One of the simulations in this study is the asteroid 300 meters (1,000 feet) in diameter, the size of six Olympic swimming pools. This is not a large asteroid, but it would still destroy an area of ​​a large city with just the initial impact. An asteroid of this size is possible; as of October 2020, scientists have discovered 9,336 near-Earth object / asteroids (NEO / NEA) that are larger than 140 meters in diameter. Among them, scientists have classified 2,122 as potentially hazardous objects (PHO). So the risks here are not astronomically low – they are more likely to fall to Earth. Scientists say NASA has found that nuclear weapons are “10 to 100 times more effective” in moving asteroids out of a collision course with Earth than alternatives. Non-nuclear, thanks to the much higher energy of fission materials than conventional materials. This energy will apply the asteroid / asteroid an appropriate force to push the asteroids / meteors closer to Earth out of their original orbit. Detonating nuclear weapons to prevent an asteroid / asteroid plunge into Earth is considered optimal and feasible; Source: popularmechanics.com There are two ways to “treat” an asteroid / meteor – disruption or deflection it. In their research, the scientists ran computer simulations to see how it could dislodge the asteroid 300 meters from its flight path toward Earth. Shattering was Armageddon’s solution – hitting the asteroid directly to shatter it into much less damaging pieces. The other way – deflector, is a more “elegant” solution, according to the researchers. This only involves redirecting the entire asteroid so that it doesn’t hit Earth, eliminating the remaining variable left behind by a broken asteroid – debris. When detonating a nucleus near an asteroid, what happens is quite simple – detonating a nuclear device above an asteroid irradiates a certain surface area. Material near the surface melted almost immediately. This small amount of superheated matter then expands out of the asteroid as “blown”, creating a pressure wave in the remaining asteroid. A rocket-like emission pulse is transmitted and the asteroid’s initial velocity is altered, deflecting the asteroid. Nuclear detonation in simulations to change the intensity of its released neutron energy, the scientists found, up to 70% of the deflector action. So if we do this in the real world, the nuclear device will liquefy part of the asteroid’s surface, creating a backlash that alters the asteroid’s orbit. It must be a nuclear device that releases neutrons, not an X-ray emitter, to be as efficient as possible, the researchers said. And while we hope we never have to use those, it’s definitely better if we know in advance that we can.
